RICHARDS, 0F WEST CHICAGO,ILLINOIS, ASSIGNORS TO THE AMERICAN PULLEY COMPANY, 0F PHILADELPHIA,PENNSYLVANIA, A CORPORATION 0F PENNSYLVANIA REEL Application led June 4,1929. Serial No. 368,855.

This invention relates to reels such as are used, for example, to spoolwire and the like, and has more particular reference to reels made fromsheet metal.

Our invention is directed in the main toward improvements whereby thecomponent parts of reels of the kind referred to are renderedself-centering incident to assembling, and capable of being readily andeasily incorporated permanently into unified structures by welding-allto the end of insuring a sturdy and dynamically balanced product withminimum expense for labor and material.

Other objects and attendant advantages will appear in the course of thefollowing detailed description taken in connection with the attacheddrawings, whereof F ig. I is a side elevation of our improved reel witha potion broken away and others in section; an

Fig. Il is an axial sectional view ofthe reel taken as indicated by thearrows II-II in Fig. I.

As shown in these illustrations the reel of our invention is constructedthroughout from sheet metal with a core bushing 5, a tubular concentricbody or barrel 6, and flat circular flange heads 7 which are centrallyapertured to engage the shouldered ends 8 of the core piece. Inconcentric association with the heads 7 are supplemental disks 9 whichare likewise centrally apertured to engage over the ends of the bushing5, and circumferentially flanged at 10 to lit snugly Within the ends ofthe body or barrel 6, thereby to center the latter in relation to theheads 7 aswell as to the bushing 5. For the sake of lightness, thelflange heads 7 and the supplemental centering disks 9 may be providedwith a number of registering openings 11, 12 in symmetric disposalaround their center apertures. The flange heads 7 may moreover beprovided with suitably allocated anchorage holes 13, 14 for wire orother strand material for which the reel is intended to be used. Whenthe parts are assembled,'it will be seen that the bushing 5 is held inplace through coaction of the shoulders .at the ends 8 with the heads 7and the associated supplemental centering disks 9.

' The body or drum 6, the heads 7.and the supplemental disks 9 arepermanently secured together preferably by welding as at 15 along theregions of mutual circumferential contact and abutment within thecorner' the welding at 17 may be done previous tc general assembling ofthe reel components, thereby in effect making the disks 9 parts of theheads 7.

Thus it will be seen that the` described novel constructionpredetermines self-centering of the parts incidental to assembling them,thereby rendering this operation easy and insuring a dynamicallybalanced structure after welding. .The absence of bolts or other specialsecuring means is not only important from the standpoint of saving inmaterial and labor costs, but favors lightness and more perfectequilibrium at high speed rotation.

While we have particularly described our invention as a reel, the use ofthis term in the appended claim is to be regarded in a comprehensivesense to include spools, pulleys or wheels generally Where a likeconstruction Would result in attainment of the several advantageshereinbefore pointed out.

Having thus described our invention, we claim:

As a new article of manufacture a reel constructed from sheet metalcomprising a core bushing having shouldered ends, a tubular body orbarrel, flat circular flange heads lightened by openings symmetricallyarranged about their centers, and correspondingly apertured supplementalfiat disks in association with the heads having inwardly directedcircumferential flanges adapted to fit perimetrically within the barrelends and thereby center the latter, said disks and heads co-acting withthe core shouldered ends and being secured together respectively bywelding along the coincidin ed es of their registerinJ openings, and rter secured likewise y welding, to each other as well as to the bod orbarrel and the core along the regions o mutual circumferential contactand abutment.

In testimony whereoffwe have hereunto signed our names in Philadelphia,Pennsylvania, this 29th day of May, 1929.
